30 Claims.

This invention relates to window assemblies, and more particularly to window assemblies having transversely arranged bars dividing the window into spaces some of which are glazed,

either with or without a group of spaces left vacant for ventilating area.

In conventional detention window assemblies as used until the last few years, guard bars were mounted exteriorly of the window assembly and independently thereof. There was no cooperation as to the structure between the guard bars and the window, the window assembly being entirely independent and separate from the guard bars. Recently another development has taken place wherein the guard bars have been removed in their entirety, the transversely arranged muntin bars of the window being spaced sufficiently close and made of sufficiently heavy material to prevent the escape or unauthorized entry of human bodies through the window. In the present embodiment the guard bars and the window have been united into a common structure, one reinforcing the other.

An object of this invention is to provide a duo- J functional assembly wherein the parts are uniquely united and interlocked into a simple but conveni nt and eificient structure that is easily constructed with a small amount of labor at a small cost, without sacrificing efficiency and durability.

Another object of this invention is to provide a closure for a ventilating area of a Window assembly that is easily assembled, that may be inserted on the job with a small amount of labor without sacrificing the efficiency or reliability.

Another object of this invention is to provide a window assembly wherein one group of muntin bars differs from another group of muntin bars, whereby one group is associated with the detention bars and the other group is offset with res set to the detention bars.

Another object of this invention is to provide a closure for the ventilating area with sufficient tolerance to permit insertion of the closure frame without extensive fitting operations and other expensive labor operations.

With the above primary and other incidental objects in view, as will more fully appear in the specification, the invention consists of the features of construction, the parts and combinations thereof, and the mode of operation, or their equivalents, as hereinafter described and set forth in the claims.

Referring to the drawings, Fig. l discloses a perspective view of the window assembly as viewed from the inside.

In the construction of window assemblies for penal institutions or where detention windows are required and in factories where ordinary windows are required, it is very desirable to have the window assembly made from parts that may be readily selected from stock and assembled on short notice so that the window assembly will not delay the work on the building. The location of the spaces left vacant for ventilating area may be selected and the closure frame inserted after the building has been completed. When this procedure is followed it is' necessary either to require very accurate workmanship, the cost of which is prohibitive, or to provide a closure and the frame therefor which has sufficient tolerances to take care of irregularities in the window structure.

The closure assemblies disclosed herein are adapted for use where the tolerances are great but at the same time providing a window assembly that is neat, is water-tight, easily assembled, cheap, and at the same time efiicient. The frame for the closure has been provided with projecting flanges which will cover irregularities, the space intermediate the flanges and the muntin bars bounding the ventilating area being concealed by putty or other suitable binding material or having the desired sealing qualities. The screen frames which oftentimes add to the clumsiness of the assembly are concealed in the present embodiment by being located intermediate the muntin bars bounding the ventilating area and the frame for the closure protecting the same. Likewise where detention bars are used it is desirable to incorporate the window structure in a unit including the detention bars. plished by providing notches in the muntin bars in which the detention bars may be seated and This may be accomwelded or otherwise secured. Instead of providing notches the transverse muntin bars may be provided with openings for the reception of the detention bars, the dimensions of the muntin bars running parallel to the detention bars being such as to permit alignment of the muntin bars with the detention bars. By so doing the massiveness of the assembly is greatly reduced.

Like parts are indicated by similar characters of reference throughout the several views.

Referring to the drawings the reference characters I II indicate the Vertical muntin bars and the reference characters I2 the horizontal muntin bars intersecting the vertical bars I I). The arrangement of these bars may be similar to that disclosed in the Bayley Patent No. 1,948,159 and the Zimmerman Patents Nos. 1,948,152 and 1,948,- 153. The transversely arranged muntin bars III and I2 divide the window into a plurality of spaces I4, some of which are glazed leaving a group of spaces I8 vacant for ventilating area. If the window assembly is to be used for detention purposes, detention bars I 8 and as extend across the ventilating area to protect the more vulnerable portion of the window assembly. The detention bars I8 and 28 may be aligned with or offset with respect to the muntin bars Ill and I2. The ventilating area I 6 is provided with a closure 22 pivotally mounted at 24 to a frame 26.

By referring to Figs. 2 and 3 it may be seen that the closure 22 is provided with glazing 28 held in position by suitable metallic jambs 33 which may be removed if it is necessary to replace the glass. The frame 26 includes the horizontal top bar 32 substantially T-shaped, having an inwardly projecting flange 34, as best seen in Fig. 2. The vertical frame members 32 are identical to the top bar 32 in cross section. The sill 36 is hooked or laid over an upwardly projecting flange 38 of the muntin bar 40 bounding the ventilating area along the bottom thereof. The horizontal and vertical members 32 are provided with L-shaped stops 42 attached thereto by welding or riveting or in any other suitable manner. The vertical stops 42 have flanges 44 arranged in abutting relation with respect to the vertical muntin bars I!) bounding the ven-.

tilating area. Likewise the horizontal member 42 has its flange 44 abutting the horizontal muntin bar I2 bounding the ventilating area at the top.

In order to secure water-tightness, the joint between the bars I II and the flanges 44 and the horizontal muntin bar I2 and the horizontal flange 44 are sealed by putty or suitable binding material or any other suitable sealing means, as shown by the reference character 46. It is to be noted that the stops 42 are medially placed with respect to the webs of the T-shaped members 32. This permits the insertion of the screen frame 50 in the pocket formed between the frame of the closure and the muntin bars bounding the ventilating area. This conceals the screen frame from the interior of the building and at the same time provides compactness, thereby diminishing the clumsiness of the window assem* bly.

Suitable inwardly projecting lugs 52 carried by the muntin bars I8 and I2 are provided with apertures receiving the bolts 54 holding the frame in a fixed relation with respect to the muntin bars, the screen 56 extending intermediate the lugs 52 and the frame 26 there being sufficient clearance between the flanges 34 and the lugs 52. The glazing in the fixed window spaces I4 is preferably located in the same plane as the glazing 28 so as to enhance the appearance of the window assembly. Instead of the lugs 52 being used, bolts 54 could either pass through or hook into the detention extending across the ventilating area.

In the modification disclosed in Figs. 4, 5, 6, and 7, the window assembly has been built around and incorporates the conventional detention bars I09. In the modification disclosed in Figs. 4 and 5 the horizontal muntin bars I82 provided with flanges I04 and I56 adjacent each end of the web I08, is provided with apertures for the reception of the detention bars I98. These bars are provided with a pair of flanges H0 and H2 cooperating to form a channel II 4 for the reception of the glazing I I6. With the exception of the muntin bars bounding the top of the window the glazing is seated in the channel H4 at the bottom that is filled with putty and located in the corner of the large channel underlying the web IIJ8. Thus it may be readily seen that the glazing may be inserted from the inside of the window assembly and rotated into position in the space between the bars I III and the normal position of the glazing H6.

To the flange II2 of the top muntin bar I58 is Welded an extension II8 that provides a seat against which the glazing II6 abuts. This permits the insertion of the glazing from the inside of the window so that the window assembly may be glazed after the building has been completed.

If a space is left vacant for a ventilating area between two of the horizontal muntin bars, the ventilating area may not necessarily extend across the entire width of the window. The ventilating area is then preferably bounded by the vertical bars I36 which may be L-shaped and suitably welded or removably attached to member I3! having one edge welded to the detention bar I 08. The glazing of the fixed spaces along side the ventilating area may be held in position by adetachably mounted member I38 held in position by screws I38 engaging the flange of the member I30. This assembly provides a fairly rigid frame bounding the ventilating area.

The closure 22 pivotally mounted in the frame 26 may be substantially identical in shape and design to the one disclosed in the modification shown in Figs. 1, 2, and 3, with the exception of the stops 42 being eliminated so that the flange of the T-shaped bar 32 abuts the flange I06 and the flange I38 bounding th ventilating area. The sill 36 in this modification is seated within member I40 provided with a dependent flange I42 mounted outside the flange H2. The frame of the closure is preferably held in position by bolts I44 engaging the lugs I46 welded to the muntin bars I88 and the L-shaped members I30. The bolts I44 pass through the frame of the screen I48 which is preferably L-shaped and projects into the pocket found between the frame of the closure and the bars bounding the ventilating area.

Referring to the modification disclosed in Figs. 6 and '7, the transverse horizontal muntin bars I 59 are provided with arcuate notches I52 in which are seated the detention bars Hit and welded thereto. Instead of the glazing extending across the entire window assembly, as in Figs. 4 and 5, vertical muntin bars I54 which may be T-shaped in cross section, interlock the transverse muntin bars I50 but the T-shaped muntin bars I54 are of lesser dimension so as to permit the alignment of the bars I54 with the detention bars I00.

In Fig. 3 the muntin bar I60 is similar to the above modifications excepting it is provided with a channel I62 and another channel |64one above and one below the web for the reception of the window panes-not shown.

From the above description it will be apparent that there is thus provided a device of the character described possessing the particular features of advantage before enumerated as desirable, but which obviously is susceptible of modification in its form, proportions, detail construction and arrangement of parts without departing from the principle involved or sacrificing any of its advantages.
